To avoid wasting system resources, dispose of this object or its parent (such as an SPSite or SPWeb) as soon as you are done using it. This object will now be disposed. Allocation Id: {5BFFCA4B-3B91-45BF-98CD-0BB508BE30EE} To determine where this object was allocated, create a registry key at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\HeapSettings. Then create a new DWORD named SPRequestStackTrace with the value 1 under this key.

To identify which code is responsible for the problem after you identified the problem you have two options:

1. You can search the earlier ULS logs for the allocation ID in the warning (if the allocation was done beyond the threshold you will find it)

2. You can follow the hints in the warning and set the following registry key as this will ensure that the stack trace of the allocation of the SPRequest object is preserved in memory and added to the 8l1n ULS log entry:

Yes you need to cretae this key “HeapSettings” and the DWORD value below it.

They do not exist after installing the product.

The second option is more reliable as it will ensure that you get a callstack for each of the 8l1n messages. Be aware that after setting this registry key you need to restart the sharepoint services and the application pools (or restart the server) to ensure that the settings get effective.

By analyzing the emitted callstack you should then be able to identify the component causing the problem.

SPDisposeCheck is a tool to help you to check your assemblies that use the SharePoint API so that you can build better code. It provides assistance in correctly disposing of certain SharePoint objects to help you follow published best practice. This tool may not show all memory leaks in your code. Further investigation is advised if you continue to experience issues.
